The Delta Force (1st Special Forces Operational Detachment-Delta), is a U.S. Army unit used for hostage rescue and counterterrorism, as well as direct action and reconnaissance against high value targets.elta Force was formed after numerous, well-publicized terrorist incidents in the 1970s. These incidents led the U.S. government to develop a full-time counter-terrorism unit. Key military and government figures had already been briefed on a model for this type of unit in the early 1960s.
Named for the fourth letter of the Greek alphabet (shaped like a triangle), a delta is a triangular area where a major river divides into several smaller parts that usually flow into a larger body of water.

Despite frequent floods, farmers often settle in a delta for this reason. Here's some more fun delta trivia: the deltoid muscles in your shoulders are named after the fourth letter of the Greek alphabet too.
